Sony Announces A7III: 4K HDR Video, 693 Point AF, 10fps Tracking

Moments ago at WPPI, Sony announced the their latest full-frame mirrorless camera, the Sony A7III. Built around the new 24.2 megapixel BSI CMOS sensor like the Sony A9, the A7III is designed for photographers such as journalists and event photographers who need to capture action quickly but with optimal image quality. The sensor boasts a 1.5 stop improvement in noise handling over its predecessor, and a 15 stop dynamic range at low ISO levels. The camera’s built in optical stabilization system provides 5 stops of shake resistance, and Sony claims that they’ve improved the color handling of the camera, particularly for skin tones.

The Sony A7III also borrows its auto-focus system from the A9, with 693 phase-detect AF points covering 93% of the frame, complimented by an additional 425 contrast-detect AF points. This system is faster and more accurate, particularly in low light, according to Sony, and Eye-Focus works even in continuous focus mode. The camera claims that longest battery life (CIPA testing standards) of any mirrorless camera at 710 shots, though the number will be much higher in real-world use, especially when using the camera’s 10 fps drive speed for shooting action.

Video shooters will appreciate the camera’s 4K video capabilities, including a Hybrid Log-Gamma profile for instant HDR playback with compatible TVs, as well as S-Log2 and S-Log3 for dynamic range and color grading flexibility. Like the A7RIII, the A7III can shoot 100Mb 120fps full-HD video, with full autofocus functionality.
